“…Due to the exceptional progress of the experiments, many non-leptonic three body B meson decays have been measured by the collaboratoins of Belle, BaBar, LHCb and so on [1]. On the other hand, to investigate the three body non-leptonic B meson decays in theories, some theoretical models are proposed, such as the SU (3) flavor symmetry framework [2][3][4][5][6][7][8][9], the heavy quark effective theory combined with the chiral perturbation theory and the final state interactions [10][11][12][13][14][15][16][17][18][19][20][21], QCD sum rules under the factorization approach [22][23][24][25][26][27], the perturbative QCD approach [28][29][30][31][32][33][34][35][36], the final state interaction formalis [37][38][39] based on the chiral unitary approach (ChUA) [40][41][42][43][44][45], and so on.…”

In the present work, we investigate the decays of B 0 s → φπ + π − and B 0 → φπ + π − with the final state interactions based on the chiral unitary approach. In the final state interactions of the π + π − with its coupled channels, we study the effects of the ηη channel in the two-body interactions for the reproduction of the f 0 (980) state. Our results for the π + π − invariant mass distributions of the decay B 0 s → φπ + π − describe the experimental data up to 1 GeV well, with the resonance contributions from the f 0 (980) and ρ. For the predicted invariant mass distributions of the B 0 → φπ + π − decay, we found that the contributions from the f 0 (500) are significant except for the ones from the f 0 (980) state. With some experimental branching ratios as input to determine the production vertex factors, we make some predictions for the branching ratios of the other final decay channels, including the vector mesons, in the B 0 (s) decays, where some of them are consistent with the experimental ones within the uncertainties.

The Dalitz plot analysis technique has become an increasingly important method in heavy flavour physics. The Laura ++ fitter has been developed as a flexible tool that can be used for Dalitz plot analyses in different experimental environments. Explicitly designed for three-body decays of heavy-flavoured mesons to spinless final state particles, it is optimised in order to describe all possible resonant or nonresonant contributions, and to accommodate possible CP violation effects.

In Standard Model, CP violation arises from an irreducible complex phase in the quark mixing matrix, now under the name Cabibbo-Kobayashi-Maskawa matrix. This description has shown remarkably overall agreement with various experimental measurements. In this review, we discuss recent experimental data and theoretical developments on three quantities of CKM matrix that are most uncertain: the V ub , including its magnitude and the phase γ in standard parametrization, and the Bs −Bs mixing phase βs.

Final state hadronic interactions and non-resonant $B^\pm\to K^\pmπ^+π^-$ decays

Abstract: We evaluate the non-resonant decay amplitude of the process B ± → K ± π + π − using an approach based on final state hadronic interactions described in terms of meson exchanges. We conclude that this mechanism generates inhomogeneities in the Dalitz plot of the B decay.
